Application Case Study: MPL-B310P-MJ74AA Servo Motor in High-Speed Packaging


MP-Series MPL 480V AC Rotary Servo Motor Application: High-speed rotary knife shaft on a Form-Fill-Seal (FFS) food packaging line.

Implementation: The MPL-B310P-MJ74AA Servo Motor controls the continuous rotary cutting blade, paired with an Allen-Bradley Kinetix 5700 drive.

Results: Leveraging the MPL-B310P-MJ74AA Servo Motor with its 5,000 RPM rated speed and low-inertia design, the machine achieves rapid acceleration/deceleration cycles for precise cutting at over 300 packages per minute. The absolute encoder eliminates machine homing cycles after power outages, while the integrated 24V DC brake immediately locks the blade during emergency stops to ensure operator safety.


Allen Bradley Servo Motor FAQ


Q: What type of feedback device is integrated into the MPL-B310P-MJ74AA?
A: The MPL-B310P-MJ74AA Allen Bradley features a multi-turn, high-resolution absolute encoder that communicates via the Hiperface protocol. This allows the Allen Bradley Servo Motor to track position accurately even during power loss, eliminating the need for axis homing cycles upon reboot.
Q: Does the MPL-B310P-MJ74AA include an internal holding brake?
A: Yes, the MPL-B310P-MJ74AA Allen Bradley is equipped with a factory-installed 24V DC electromagnetic holding brake. This configuration makes the Allen Bradley Servo Motor ideal for vertical axes or suspending loads where stopping shaft rotation during power-off states is critical for machine safety.
Q: Which Allen-Bradley servo drives are compatible with the MPL-B310P-MJ74AA?
A: The MPL-B310P-MJ74AA Servo Motor natively pairs with the Kinetix platform, including the Kinetix 5500, Kinetix 5700, and Kinetix 6000 series. When integrating the Allen Bradley Servo Motor into a Kinetix 5500 or 5700 system, a feedback converter kit like the 2198-H2DCK is required to convert its Hiperface signal to a single-cable DSL format.
Q: What are the primary operating limits and shaft mechanical specs of the MPL-B310P-MJ74AA?
A: The MPL-B310P-MJ74AA Servo Motor operates on a 460V AC voltage class and delivers a maximum rated speed of 5,000 RPM. Mechanically, the MPL-B310P-MJ74AA Servo Motor is designed with a 100 mm frame size, low-inertia rotor, and a keyed shaft extension.
